# ============================================================
# IotLCM 对外入口 nginx 配置示例
#
# 作用：把多个服务按路径分流到统一域名下。
# 若宿主机已有 nginx 或面板，可不启动本容器，
# 把下面的 location 段落并入宿主机配置即可。
#
# 把 your-domain.example.com 替换为你的实际域名。
# ============================================================

# ---------- 后端地址解析 ----------
# 这些 upstream 写的是 compose 服务名。nginx 默认只在**启动时**解析一次，
# 容器重建后 IP 变了就会持续 502（需重启 nginx）。resolve + zone 让它在运行期自动跟随。
# 注意：127.0.0.11 是 Docker 内置 DNS，仅在容器内有效：
#   ・在容器内用本文件   → 保持下面的 resolver 不动
#   ・把本文件并入宿主机 nginx → 把 resolver 换成宿主机 DNS（或删掉 resolver 与各 upstream 的 resolve 参数）
resolver 127.0.0.11 valid=10s ipv6=off;
